Taylor Swift & Katy Perry Feud A Grammy ‘Nightmare’

From seating charts to celebrities mingling backstage, Grammy producers devised a specific setup and schedule for the feuding pop stars!

“It’s been a nightmare co-ordinating everything so Katy and Taylor don’t cross paths at all. That means that the seating plan, backstage areas, and even the walk up to the stage at all times need to keep the girls well apart. They [didn’t] want this year’s Grammys to be remembered as the time the girls had a massive run-in,” according to the Daily Mirror.

Fortunately, it seemed like a cat fight was avoided between the mutual kitty lovers.
